CVE-2026-82292: NULL pointer dereference vulnerability in QDomDocument::setContent() XML parsing impacts Qt
Noroxi assessment
Priority: Monitor (action score 7/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: qt qt 6.11.3, 6.8.9.
Low priority for now. Upgrade to qt qt 6.11.3, 6.8.9 or later.
